SPECIFICATION forming part of Letters Patent No. 468,763, dated February 9, 1892.

Application filed July 28, 1890.

To all whom it may concern:

Be it known that I, LEON DONNE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in 'lesting-lvlachines, of which the following is a specification.

The object of the present invention is a machine for indicating the force of a blow struck [O with the fist, a kick, or a stamp with one or both feet, the machine being provided (in addition to a graduated dial and index) with a suitably-marked fly-wheel, which is put in rapid rotation by the blow and continues to rotate until its momentum is spent.

The invention consists in certain features of novelty that are particularly pointed out in the claims hereinafter, a machine embodying said invention being first fully described with reference to the accompanying drawings, which form a part of this specification, and of which- Figure 1 is a front elevation of the improved machine. Fig. 2is a rear elevation of the internal mechanism thereof. Fig. 3 is a sectional elevation thereof looking rearward, the cutting-plane of the section being just insideof the front wall of the casing. Fig. 4 is a sectional elevation thereof, the section being in two planes, one in the center and the other to one side of the center of the machine, the principal parts being shown in side elevation. Fig. 5 is a section showing the coin-receptacle in detail. Fig. 6 isa sectional elevation show ing in detail the displaoeable tongue and its accessories. Figs. '7 and 8 are views showing details.

Upon the outside of the front wall 1 of the casing is a graduated dial 2,which is swept by an index 3, the shaft at of which is journaled in a suitable support and has secured to it inside the casing a pinion 5, which meshes with a rack formed on a vertical plunger 6, whose upper end is secured to a piston 7, fitting loosely in a cylinder 8, the lower end of which is open, while the upper end is closed air-tight and secured to the top of the casing. To the shaft at is also secured a ratchet-wheel 9, with which engages a dog 10 anda pawl 11, the latter for rotating it and the former for Serial No. 360.128. (No ma.)

preventing its retrograde movement. The pawl is fixed to the end of a lever 12, which is fulcrumed to an arm 13 of the frame and rests upon and derives its motion from a cam 14, secured to a second shaft 15, journaled in suitable supports beneath shaft 4. To this second shaft is secured a solid disk 16, constituting a fly-wheel, situated just back of the front wall 1 and visible only in part through an opening 17 therethrough. As shown in the drawings, the opening falls Within the periphery of the dial, and both are covered and protected by a pane of glass. To the shaft15 is secured a ratchet-wheel 18, which is engaged by a rackbar 19, hinged to and depending from a lever 20, one end of which is fulcrumed to a suitable support and the other provided with a weight 21. A spring 22, fixed at one end to the lever 20 and at the other engaging a lug or short arm 23, projecting laterally from the upper part Of the rack-bar, tends to hold it normally in engagement with the ratchet-wheel 18. A springdog 24. engages the ratchet-wheel, so as to prevent it from being turned by the friction produced by the ratchet-bar against it as the lever 20 is elevated. As the lever descends the teeth of the rack-bar successively engage those of the ratchet-wheel and impart to the shaft and its accessories a more or less rapid rotation, according to the height from which the lever falls. hen the lever is at its lowermost posit-ion and rests upon a stop 24, a cut-away portion 25 of the bar 19 is opposite the ratchet-wheel, and a guide 26, through which the bar passes, holds it out of contact with said Wheel, so that after the lever has come to rest the shaft and its accessories may continue to rotate by reason of the momentum of the fly-wheel 16, acquired during the descent of the lever. 0

Situated beneath the lever 20 is a rod 30, which is capable of sliding vertically, suitable brackets 31 being provided forguiding it and confining it against lateral movement. This rod can be elevated by the upward movement of either one of three levers 32, 33, and 84, which are fulcrumed to the case and pass through slots 27, 28, and 29, respectively, formed through the rod. The slots are so located that when the parts are in their normal positions each lever occupies the upper end of its slot, (the ,rod being supported by the levers,) and each slot is of such length that said rod may be elevated to its highest possible position by either one of said levers without disturbing the positions of the others.

The levers themselves may be elevated by as many separate devices from the outside of the casing. The lever 32 rests upon and is supported by a stem 35, which is supported by the frame so as to be capable of endwise movement and passes out through the front wall of the casing. Surrounding the stem and bearing at one end against it and at the other end against the frame is a stout spring 36, which tends to hold the stem normally in its outermost position, its outward movement being limited by a second shoulder, which comes in contact with the front of the casing. On the top side of the push-stem, extending outward from the lever v32, is a cam 37, which when the said stem moves'inward impinges against the under side of the lever and elevates it, thereby elevating the rod 30. Upon the outer endof the stcm'is secured an enlarged head '38, which is well padded and is designed to be struck with the fist, said head being prevented from rotating by any suitable meansas, for example, one or more pins secured to the under side of the head and entering corresponding perforations formed: through'the front wall of the casing. Surrounding the head is an annular pad 39 for protecting the fist of the striker in case it should miss or glance off from the head. 7

The parts numbered 35, 36, 37, 38, and 39 are respectively duplicates of the parts numbered 35 to 39, inclusive, the parts'35 850., being arranged in the same relation to the lever 33 as the parts 35, &c., bear to the'lever 32. The padded head 38 is situated at about the height of a mans breast, while the padded head 38 is situated about knee-high,

or a little lower, and is designed to be kicked.

Situated beneath the head 38 is a heavy lever 41, passing through the front wall of the casing. Its inner end engages the under side of lever 34, while its outer end is provided with a platform 42 of sufficient size to receive both of a mans feet at one time. This platform is held normally in its elevated position by a heavy spring 43, which is situated beneath itrand rests on the heavy iron baseplate of the machine.

By striking the head 38, or bykicking the head 38,'or by stamping with one or both feet, or jumping upon the platform 42, the vertical rod 30 will be elevated agreater or less distance, according-to the extent of the movement of the device that receives the blow, which movement will be proportional to the extent of the compression of the spring (36, 36, or 43, as the case may be) that resists the blow, said compression being of course proportional to the force of the blow. When the rod 30 is connected with the lever 20 (by mechanism presently described) at the time the blow is struck, said lever will be thrown upward a distance proportional to the force of the blow, and in descending will set the fiy-wheel 16 in motion at a speed proportional to the distance it descended, the number of revolutions made by said fly-wheel being proportional to its initial speed, and the extent of the movement of the index 3 proportional to the number of revolutions of the fly-wheel. Thus the extent of the movement of the index and the number of revolutions made by the fly-wheel are proportional to the force of the blow. This operative connection between the rod 30 and lever 20 can be established by the mechanism now to bedescribed when a coin of proper size is introduced, the coin itself forming an operative part of such mechanism. .The coin is'introduced through a slot-opening 44 at the front of the machine, whence it passes by gravity through a chute 45 to a coin-receptacle 46,

which latter, in fact, forms one arm of abellcrank lever, the other arm of which is shown 'at 47. The outline of the cross-section of the arm 46 is rectangular, andthrough one of its side walls is formed a slot 48, which, when the partsarenormahis opposite the open end of the coin-chute 45 and permits the coin to pass to the interior of the receptacle.-

Through the front. and rear Walls of the receptacle are cut slots 50, which are situated opposite each other and extend to the end of the arm, reducingit in effectto a pair of channel-irons situated ashort distance apartand with their hollow sides toward each other, thus E 3. To retain. the coinwithin this receptacle until it has performed its proper function, a spring-tongue 51 is fixed to the side wall of the casing in such a position as to project into the slot 50 and cross the channel of the receptacle below the slot 48.. A shaft 52rextends through the front wall of the casing and is provided on its front, end with a hand-crank 53, whereby it may be turned. On the inside of the casing this shaft is providedwith a ratchet-wheel 54, with which engages a spring-pawl 55 to pre vent its being turned in one direction. Upon it is also an arm 56, which is situated directly opposite the slot 50. \Vhen there is no coin in the receptacle, the shaft-52 may be turned freely in the direction of the arrow without affecting the lever 46 47, the spring-tongue 51 being pressed back by the arm 56, which moves in slot 50,

\Vhen there is a coin in the receptacle 46, the end of the arm 56 will come in contact with its fiat side, while, a toe 57, projecting from the end of the arm, will engage the pe-' riphery of the coin from above. The lower portionof the arm 46 occupies a position tangential to the path of the arm 56, and consequently as the arm 56 is rotated, carrying with it the coin which bears against the rear wall' of the receptacle, the arm 46 will be moved to the position shown by dotted lines, producing a corresponding movement of the instantly restored to its former arm 47. The coin engaged by the toe 57 is expelled as soon as it reaches the end of the receptacle, and thereupon the lever 46 4:7 is position by a spring 58. I

To the free end of the arm 47 is pivotally connected the lower end of a rod 59, whose upper end is provided with a cam 60, for a purpose that will appear presently, The rod 59 has a tooth or shoulder 61 and passes through a slot formed through a horizontal arm 62 of a tri-armed lever, the other arms of which are indicated by the numerals 63 and 64., respectively. \Vhile the parts are in normal position the shoulder 61 is above the arm 62; but when the position of the lever 46 47 is changed it draws the rod 59 down until its shoulder is below the arm 62. Then when the lever 46 47 is restored to itsnormal position the rod 59 is thrust up to its normal position. In rising the'shoulder 61 engages the arm 62 and moves the tri-arm lever about its fulcrum to the position shown by dotted lines. When the tri-arm lever has reached this position and before the rod has completed its upward movement, the cam 60 will come in contact with the shaft 15, and the 3 farther upward movement of the rod will cause the cam to move its upper end laterally and thereby disengage the shoulder61 from the arm 62, leaving the tri-arm lever for the instant in the position shown by dotted lines. Hinged to the upper end of rod 30 is a tongue 65, which rests normally out of alignment with said rod, as shown by dotted lines in Fig. 6. Projecting beneath this tongue is one end of a lever 66, the other end of which is connected by a link 67 with the extremity of the arm 63. WVhen the tri-arm lever is moved from the position shown by full lines to that shown by dotted lines, the lever 66 lifts the tongue to the position shown by full lines-that is, places it in alignment with the rod 30, with its upper end in engagement with the underside of the weighted lever 20 thus establishing operative connection between the rod and the lever.

Normally the plunger and piston 6 and 7 are held elevated by the engagement of the dog 10 and pawl 11 with the ratchet-wheel 9; but the movement of the tri-arm lever 62 63 64 to the position shown'by dotted lines causes a cam 68, formed on its bent arm 64, to shift a bent lever 69 from its position shown in full lines to that shown in dotted lines. In so doing said lever 69 presses both the dog 10 and pawl 11 out of engagement with the ratchetwheel 9, permitting'the plunger to fall. In falling it restores the index 3 to zero and also strikes the arm 64 with suliicient force to restore the levers 62, 64:, 66, and 69 to their nor mal positions, thereby permitting the dog 10 and pawl 11 to re-engage the wheel 9, but leaving the tongue 65 in engagement with the lever 20. The device is then in condition for operation, and a blow on either of the heads 38 or 38 or on the platform 32 will cause a Sudden upward movement of rod 30 with. the result already described. The suddenness of the upward movement of the lever 20 causes it to move away from the tongue 65 as the upward movement of the latter ceases, and in so doing a cam 70 on said lever impinges againsta shoulder 71 on the end of said tongue and throws it out of alignment-with the rod 30, whereupon it falls by gravity to its normal position. A stop prevents the tongue 65 from moving too far. The stop is so situated that the tongue can be moved by lever 66 a little beyond vertical position, so that it will be held in its upright position by gravity.

In machines of this character as heretofore constructed the index is so connected with the impact device that its movement from zero to the point indicating the force of the blow is so rapid that it cannot be followed with the eye. In the machine that forms the subject of thisapplication the movement of the index will be slow, gradually decreasing in speed from start to finish. After the blow is struck the index remains at the point to which it was moved by the blow until another coin is deposited and the handle 54 turned to set the machine for the next operation.

The outer face of the fly-wheel 16 may be provided with words, letters, figures, pictures, advertising-cards, in short, any desired symbols, arranged in any desired manner,

either arbitrarily oraccording to some system. I propose to divide it off into a number of spaces or segments and place in each space a picture and accompanying each picture an advertising-card. For example, in one space will be placed the picture of a pugilist and the advertisement of a dealer in boxinggloves, in another the picture of an oarsman and the advertisement of a shell-builder, and so on, using any pictures or other symbols. The various spaces have well-defined marks of division on the periphery of the wheel, and a pointer 75, projecting downward from the top side of the opening 17, indicates which space is uppermost when the wheel stops.

The term indicator is used in this specification in a generic sense, meaning any device for indicating or showing the effect produced by the operation of the device, and the term fly-wheel is used to denote a wheel free to rotate by its momentum afterthe device which set it in motion has come to rest.

Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent- 1.
